At the NFL Combine in Indianapolis, SEC athletes posted some impressively small numbers in the 40-yard dash. AL.com's Randy Kennedy and Mike Herndon address the topic in their latest "SECond Look" video report about football in the SEC.

Former Auburn running back Onterio McCalebb's official time was 4.34 seconds, which tied West Virginia's Tavon Austin for second-fastest of the 2013 NFL Combine. That performance has generated a lot of talk, including a flurry of interest in social media tied to an earlier, unofficial posting of 4.21 seconds for McCalebb's dash.

Former Alabama defensive back Dee Milliner similarly impressed with a 4.31, which was later officially adjusted to 4.37 seconds.

Everybody's talking about the numbers, but how much of a difference does the dash make?

Says Herndon, "When you have a guy like Dee Milliner, you expect him to run fast. It confirms what you already know about him, For some guys, it probably is more of a factor than others."

One player, for example, needed a fast dash but did not achieve it. Will that hurt his chance to get into the draft's first round?

And, overall, why is the speed seemingly getting better each year?

Kennedy asks Herndon, "Do you think it's ... guys being on the track training? Or what do you attribute that to? Just better athletes?"
